A novel approach to the Cu-catalyzed cyanation of simple arenes using acetonitrile as an attractive cyano source has been documented. The C–H functionalization of arenes without directing groups involves a sequential iodination/cyanation to give the desired aromatic nitriles in good yields. A highly efficient Cu/TEMPO system for acetonitrile C–CN bond cleavage has been discovered. TEMPO is used as

The intramolecular photoreaction of 2-cyanonaphthalene with styrene afforded tricyclo compounds in yields of up to 68 % via photo cyclo adducts at the 1,8a-position of the naphthalene ring. Photoreactions between naphthalene and alkenes are known to proceed at various positions on the naphthalene ring. However, selective reaction at the 1,8a-position was achieved for the first time by appropriate design

Disclosed is the use of an adhesion molecule inhibitor that is effective in the prevention and treatment of inflammatory diseases caused by infiltration of leukocytes such as monocytes, lymphocytes and eosinophils, by inhibiting cell infiltration which mediates adhesion molecules, especially adhesion molecule VLA-4.
Since the spiro acid derivatives according to the present invention are excellent in the effect of inhibiting cell adhesion via adhesion molecules, especially adhesion molecule VLA-4, they are useful as therapeutic drugs against various inflammatory diseases. For example, provided are the spiro derivative and the adhesion molecule inhibitor which includes as an active ingredient the spiro derivative as shown by the below formula (18).
